FIXING WEAR & TEAR ON A VALVE – CASE STUDY

EVENT REPORTED by SAM GUARD®

• A valve was not closing properly, which led to a lack of control over the material’s flow

Measurement Tags Alerted

• Valve opening position
• Slave valve
• Set point

How SAM GUARD® Helped

• Sent an alert indicating strange behavior of valve EFC2702
• The opening position of the slave valve started fluctuating up to 100% while the master set point was absolutely stable.

COST / DOWNTIME AVOIDED

• Upon first inspection it was found that the valve was not closing under 8%
• After calibration it was discovered that the valve was not sealing, so it was replaced and underwent an overall mechanical review
• Deeper inspection found significant wear and tear on the plug, which clearly needed to be replaced.
• Regaining control over the flow of material prevented waste of unnecessary material and helped safeguard the quality of the end products.
